Problems solved by technology

At present, a few manufacturers of oil-resistant and flame-retardant conveyor belts in China have started production, but in the actual production process, on the one hand, air bubbles are easily generated inside the covering rubber, and surface defects such as bright scars are prone to occur on the surface of the covering rubber, which makes the surface quality of oil-resistant and flame-retardant conveyor belts poor. Qualified, it is difficult for users to accept, and the phenomenon of rejection and return often occurs, which brings many tangible economic losses and intangible brand image losses to oil-resistant and flame-retardant conveyor belt manufacturers; The phenomenon of delamination between the covering glue and the fabric core affects the service life of the conveyor belt. Manufacturers of oil-resistant and flame-retardant conveyor belts often receive complaints from customers and recall their own oil-resistant and flame-retardant conveyor belt products. In view of this situation, this invention came into being

Abstract

The invention relates to a general-purpose fabric core flame-retardant oil-resistant adhesive for a conveying belt and a preparation method thereof, and belongs to the technical field of flame-retardant oil-resistant conveying belts. The adhesive comprises butadiene-acrylonitrile rubber, butadiene-styrene rubber, natural rubber, carbon black, white carbon black, aromatic hydrocarbon oil, calcium carbonate, a flame retardant, an anti-aging agent, an adhesive, tackifying flame-retardant resin, an ultra-zinc active agent and sulfur. The general-purpose fabric core flame-retardant oil-resistant adhesive is prepared through preparation of a first-stage rubber compound, preparation of a second-stage rubber compound, preparation of a third-stage extrusion rubber compound and vulcanization. The provided adhesive simultaneously meets two standard requirements: a GB / T10822-2014 general-purpose fabric core flame-retardant conveying belt and an HG / T3714-2014 oil-resistant conveying belt, and the preparation method disclosed by the invention has the advantages of simple steps, easiness in operation and the like.

Description

technical field [0001] The invention relates to a glue for a general-purpose fabric core flame-retardant and oil-resistant conveyor belt and a preparation method thereof, belonging to the technical field of flame-retardant and oil-resistant conveyor belts. Background technique [0002] The conveyor belt is a large composite material product composed of rubber covering rubber material, skeleton material and interface bonding material. At present, a few manufacturers of oil-resistant and flame-retardant conveyor belts in China have started production, but in the actual production process, on the one hand, air bubbles are easily generated inside the covering rubber, and surface defects such as bright scars are prone to occur on the surface of the covering rubber, which makes the surface quality of oil-resistant and flame-retardant conveyor belts poor. Qualified, it is difficult for users to accept, and the phenomenon of rejection and return often occurs, which brings many tangi...
